Road bike BB and crank help

[W@nted]

Hi.

please assist. Bicycle (ckt frame) currently has a BB386 pressfit BB installed with a Shimano 105 crankset 24mm spindle. 
 

I want to install a Sram red crankset. The sram crankset spindle has about 2mm play, so I need a different BB/spacers. 
 

Not a fan of the spacer route, so will the normal Sram gxp pressfit road BB be correct?

You need this. Will work fine.

I have tested this on a bike with BB386.

Thanks, where did you buy the spacer?

I have a few, one my mate made at work from this diagram. The others I bought from Aliexpress.

I understand Shimano crankset with BB386 is not a pressfit crankset, it is normal Shimano and the BB386 has adapters for the normal 24 mm Shimano crankset to fit. I know the 24/22 GXP does fit with this adapter I have. I don't know if a pressfit GXP crankset will fit with the BB386, test it first before you buy anything.
